Slip rings are susceptible to corrosion and therefore susceptible to failure and require maintenance.

- Physical repatching of Coils is an efficient electronic control method to effectively extract energy from wind and other small variable generation sources. Physical repatching avoids voltage drops across semiconductors and parasitic power drains in switching circuits.
- Such a low rpm generator will be able to take advantage of lower winds because it can use the dense turbine blade disks associated with water pumping wind generators. The low tips speeds of the wind turbines make the wind turbine quieter.

- the zig zag winding of single strands circulating around the periphery with an air core magnetic circuit is the primary design described here, as this is lightweight, the magnets are permanent and the total expected power is low.
- prewound coils that span two opposed slot sets as 4 winding slots in total could allow a more conventional salient or lapped pole generator/motor winding to be accessed from the exterior.
- the box closure pieces 7 could be make of magnetically conductive materials which could have protrusions through the center of the coils to form poles of magnetic circuits. These closure pieces could be made of 2d stacks of thin sheets of magnetically desirable steels to form the cap and pole protrusion utilizing a of a 2d manufacturing method.

- The invention comprises a larger than conventional diameter electric generator that is designed to operate at lower revolutions per minute than conventional generators so as to be able to be driven by human legs or arms or wind generation at low wind speeds, or water movement at low or zero water drop distance or ‘head’ or other applications A larger diameter and less wide low rpm generator which is designed to be constructed by 2 dimensional cutting of flat stock materials.
- Ideally the invention would be able to be capable of generating electricity without batteries in the system. It should generate power in the lowest wind speeds. Rapid design variation and field modification should be inherent. Low Audio and RF noise is desirable. Therefore it is desirable to avoid Slip rings which can cause sparks and there for explosions and radio interference. Slip rings are susceptible to corrosion and therefore susceptible to failure and require maintenance. The generator/alternator achieved will be quieter, and there for be less disruptive to the people working in proximity. A reduction gear or drive will not be required, with resulting decreases in noise and efficiency losses compared to gearboxes and chains etc.
- The generators rotor must have the largest possible diameter to achieve usable voltages in the smallest of winds, and the low human pedaling speed and low head water wheel speeds. Physical repatching of Coils is an efficient electronic control method to effectively extract energy from wind and other small variable generation sources. Physical repatching avoids voltage drops across semiconductors and parasitic power drains in switching circuits.
- Such a low rpm generator will be able to take advantage of lower winds because it can use the dense turbine blade disks associated with water pumping wind generators. The low tips speeds of the wind turbines make the wind turbine quieter.
- The ability to generate usable power in the lowest winds is a different definition of efficiency, in the sense of having power when you need it, without relying on heavy and expensive batteries to store energy between hoped for high wind episodes required by other generators.
- To generate large wattages from a human for long periods of time, large amounts of cooling are necessary, most practically by wind. The addition of a large fan for cooling the rider will increase total work output by perhaps 20 fold per session. Humans emit perhaps 80% waste heat similarly to a passenger car, so humans over heat if you run them hard standing still as a passenger car does. Probably All exercise machines should have large user controlled fans.
- Possibly the same fan that is used for the Wind Generation could be applied as a cooling blower during doldrums where human generation may be required.
- In summary a low rpm generator has many applications, such as low speed wind of the historical water pumping turbine style and historical grain grinding “sail” style, human and animal power, low head water power such as surface flow using a floating paddle wheel concept and wave powered buoys
- The generator's edge shape is made up of flat or
planar sections 7 of sufficient quantity to have some circularity, that is to say as a polygon of equal sides whose junctions fall on the same circle, a regular convex equiangular polygon. This design facilitates access to open slots for winding placement. The zig zag winding of single strands circulating around the periphery with an air core magnetic circuit is the primary design described here, as this is lightweight, the magnets are permanent and the total expected power is low. - Other configurations are possible such as prewound coils that span two opposed slot sets as 4 winding slots in total could allow a more conventional salient or lapped pole generator/motor winding to be accessed from the exterior.
- Alternate configurations of more conventional circular windings could be built around two of these deeper cuts for single phase poles or across many cuts for multiphase winding schemes, wherein it is probable that magnetically conductive core material would be preferred to form the stator, layers of which could be stacked between the side panels in lieu or in addition to the generator box closure of drawing 13 etc, which is presently not shown in these drawings which focus on non magnetic structural materials and air cored windings.
- The
box closure pieces 7 could be make of magnetically conductive materials which could have protrusions through the center of the coils to form poles of magnetic circuits. These closure pieces could be made of 2d stacks of thin sheets of magnetically desirable steels to form the cap and pole protrusion utilizing a of a 2d manufacturing method. - Other designs polygonal designs with unequal sides that do not fall on the same circle could allow the creation of shapes of footings for the generator, and stair cases to climb the generator, however the externally accessed slots would become very deep and less convenient.
